Jeremy Corbyn's brother Piers endorsed Donald Trump's right to re-tweet far-right propaganda and himself re-posted a message from a former BNP activist.

Piers Corbyn, who describes himself as a 'long rage weather and climate forecaster', posted a Twitter rant claiming the US President was only interested in publicity.

He said Mr Trump was seeking to prove politicians were more interested in attacking him rather than the content of the messages.

The older brother of the Labour leader also reposted a Tweet from Mark Collett, a former BNP activist, that attacked Theresa May as an 'Islamic appeaser'.

In his own tweet, Mr Corbyn said: 'PEOPLE! WAKE UP. MyTake is #Trump deliberately ReTweeted from someone who he knew would cause offence in order to magnify publicity and expose many politicians in front of the people for attacking the messenger (him) rather than discuss the content of the news concerned.'

The message from Mr Collett, a former chairman of the Young BNP, posted a photograph of Theresa May wearing a headscarf.

And his tweet read: 'Theresa May is an utter disgrace. She is an Islamic appeaser, multiculturalist & pawn of the internationalist bankers.
